CCD observations of IT Her (GSC 2112 1845) were obtained at my private observatory over a period of 7 nights during 2010. 704 images were collected. They confirm, that IT Her is an eclipsing binary of type EW with an amplitude of 0.45 mag as already shown by Schmidt et al.,(1996), Diethelm (1999) and Kreiner (2004). Its period is not stable but extended, with the best elements: JD 24452500.0940 + 0.3393964 d*E. The secondary minimum is at phase 0.5. Both minima show a contstant brightness of 0.025 ±0.003 d.
